Question

Explanation:

To determine the largest known gravitationally bound structure, we analyze each option:

• Solar system: Consists of the Sun and its orbiting bodies, relatively small.
• Galaxy: A collection of stars, gas, etc., but smaller than a cluster.
• Local group: A group of galaxies, but clusters are larger groupings of galaxies.
• Cluster (galaxy cluster): A large assemblage of galaxies bound by gravity, larger than the other options here. Among the given options, a cluster (galaxy cluster) is the largest gravitationally bound structure.

Answer:

Cluster
